Dual-speed capability (1800 r/min low speed and 3600 r/min high speed) provides broad process control in a single motor, reducing parts inventory and installation time. This translates to measurable efficiency gains on shop floor conveyors, grinders, and small lathes as throughput improves without changing hardware. The 115 V, 1-phase, 60 Hz design matches standard facility power, lowering wiring costs and simplifying integration with existing controls. The TENV enclosure and insulation class B enhance reliability in typical workshop environments, minimizing dust ingress and thermal stress to extend motor life. Foot-mounted orientation and a 0.38 in shaft diameter support straightforward installation, alignment, and compatibility with common belts and pulleys, while 2P/4P pole configurations offer flexibility for different load profiles. CSA and UR certifications underpin compliance and risk management, easing procurement and commissioning for industrial buyers. Stocked at multiple warehouses and backed by a straightforward warranty framework, this motor supports reduced downtime and faster project realization in grinders, buffing stations, and small machine tools.

FAQs
Yes. The 7B340 is a 115 V, 60 Hz, single-phase motor designed for direct-on-line starting. It fits standard shop power and typical belt-driven or pulley-laden equipment, simplifying installation and reducing the need for specialty transformers or controls. This compatibility supports quick retrofits and minimal wiring changes during modernization projects.
The motor provides two speeds: 1800 r/min (low) with 0.06 HP and 3600 r/min (high) with 0.25 HP. The current draw is approximately 2 A on the low-speed setting and 2.9 A on the high-speed setting, enabling appropriate drive sizing for light-duty grinders, buffers, lathes, or belt sanders without overloading the circuit.
This dual-speed motor is well-suited for grinders, buffers, lathes, and belt sanders in small to mid-size workshops. Its 1-phase, 60 Hz operation and compact footprint support integration into existing benches or compact tool stations, while the two-speed capability provides operational versatility across finishing and material removal tasks.
The ABB 7B340 carries CSA and UR certifications, indicating compliance with recognized safety standards for North American operation. This, combined with a 40 °C ambient rating and a TENV enclosure, supports safe installation in typical workshop environments and simplifies procurement for regulated projects.
Maintenance is straightforward due to the simple, direct-on-line single-phase design and standard 115 V supply. The dual-speed capability reduces the need to stock multiple motors, cutting both purchase and maintenance costs. Stocked availability across warehouses minimizes downtime, while the compact footprint and robust steel frame contribute to longer service intervals and a faster return on investment for small machine upgrades.
